The problem of finding stabilizer quantum-error-correcting codes can be transformed into the problem of finding classical self-orthogonal linear codes over the Galois field GF(4) under a Hermitian inner product. A classical cyclic code over the field GF(4) is self-orthogonal with respect to the Hermitian inner product iff the generator polynomial of its dual code is a factor of its generator polynomial.

寻找量子稳定子码的问题可以转化为寻找GF(4)上厄米内积自正交的经典线性码的问题；对于GF(4)上的经典循环码，它是厄米内积自正交的，当且仅当它的对偶码的生成多项式是其生成多项式的因子。

This new problem is called extended problem which can be solved by the dual simplex method.

这个增加了约束的新问题叫做扩充问题。

Some constraints are selected, and omitted according to the most-obtuse-angle principle. The smaller problem is solved with the simplex method. Then the omitted constraints are added to restore the original problem. If all the constraints are satisfied, then a basic optimal solution is reached. In the other case, the dual simplex method is used to obtain the basic optimal solution.

该算法依据最钝角原理略去部分约束得到一个规模较小的子问题，用原始单纯形算法解之；再添加所略去的约束恢复原问题，若此时全部约束条件均满足则已获得一个基本最优解，否则用对偶单纯形算法继续求解。
